PHOENIX (AP) — Lori Vallow Daybell, who was convicted of killing her two youngest children and conspiring to murder a romantic rival, is on trial again Monday. This time, she's accused in Arizona of conspiring to murder her estranged husband.

In opening statements the prosecution said that Vallow Daybell conspired with brother Alex Cox to kill Charles Vallow and cash in on a life insurance policy, while espousing the belief that Charles was possessed by an evil spirit.

The case has drawn significant public attention in part because Vallow Daybell, 51, has doomsday-focused religious beliefs. She isn’t a lawyer but has chosen to represent herself in the six-week trial.

Vallow Daybell has pleaded not guilty and has not spoken publicly about the details of Vallow’s death. Here’s what to know about the case.

What happened at the start of the trial

“Lori Vallow is why Alex was able to shoot Charles,” prosecutor Treena Kay said. “Lori Vallow is why Charles is dead.”

A jury of 16 took their seats in a Phoenix courtroom, including four alternate jurors. Kay provided a detailed timeline and argued that phone records, witness testimony and forensic evidence will show that Cox’s shooting of Charles was “not self defense.”

The prosecution also said Monday that Vallow Daybell conspired in the killing so that she could move forward with marrying her then-boyfriend Chad Daybell, an Idaho author who wrote several religious novels about prophecies and the end of the world.

“Lori Vallow wanted to be Lori Daybell, wife of Chad Daybell, and in July 2019 Lori Vallow wanted to keep the same lifestyle that she had with Charles. And she could get all of this if Charles was dead,” Kay said. “She could marry Chad Daybell and become Lori Daybell. She would get a million-dollar life insurance policy.”

What happened in Arizona

Vallow was fatally shot in July 2019. Vallow Daybell then moved to Idaho with two of her youngest children and married Daybell just two weeks after the death of his wife, Tammy Daybell. The bodies of the children, 7 and 16, were later found buried in rural Idaho on Chad Daybell’s property.

Vallow Daybell is already serving three life sentences in Idaho for the children's deaths and for conspiring to kill Tammy Daybell. Chad Daybell was sentenced to death in the three killings.

Four months before he died, Charles Vallow filed for divorce from Vallow Daybell, saying she had become infatuated with near-death experiences and had claimed to have lived numerous lives on other planets.

He alleged she threatened to ruin him financially and kill him. He sought a voluntary mental health evaluation of his wife.

Who fired the gun

Police say Vallow was fatally shot by Alex Cox, in a Phoenix suburb. Vallow Daybell’s daughter, Tylee, told police that she confronted Vallow with a baseball bat after she was awakened by yelling in the house.

Tylee said she was trying to defend her mother, but Vallow took away the bat, according to police records. Cox told police that he fired after Vallow refused to drop the bat and came after him.

Cox told investigators that Vallow Daybell and the children left the house shortly before the shooting.

Cox, who claimed he acted in self-defense and wasn’t arrested in Vallow’s death, died five months later from what medical examiners said was a blood clot in his lungs. Cox's account was later called into question.

What is Lori Vallow Daybell's background

Vallow Daybell was a beautician by trade, a mother of three and a wife — five times over.

She married Vallow in 2006, and later adopted JJ, but by 2019 their marriage had soured. The two were estranged but still married when Cox fatally shot Vallow.

Public interest from around the world only grew as the investigation into the missing children took several unexpected turns, each new revelation seemingly stranger than the last.

Daybell, who was once a contestant on “Wheel of Fortune,” has been the subject of a Netflix documentary and Lifetime movie.

“I want to see how she commands the courtroom,” said Bill Hurley, a spectator who jockeyed for a spot in the packed courtroom gallery. Some, like Hurley, have been following the case since 2021.

How she's fighting the case

While representing herself, Vallow Daybell has complained about news coverage of her criminal cases, invoked her right to a speedy trial, questioned whether a government witness was truly an expert and engaged in disputes over the pre-trial exchange of evidence.

At a hearing last week, she lost a bid to strike three people from the prosecution’s witness list, including the grandmother of her adopted son. Another witness says Vallow Daybell spoke about Vallow as being “possessed” in the months before his death. When the judge asked her to argue her point, Vallow Daybell lowered her head, sighed and paused a few seconds. “Their information is not firsthand," Vallow Daybell said. "These witnesses are all coming together. They are watching everything that goes on on TV regarding this.”

If convicted in Arizona of conspiring to kill Vallow, she would face a life sentence.

Vallow Daybell will wear civilian clothing during her trial and will not be handcuffed or shackled when jurors are in the courtroom. She, however, is expected to be wearing a belt-like device under her clothes that will let a jail officer deliver an electric shock by remote control if there's a disturbance.

Who was killed in Idaho

The Idaho investigation began at the end of 2019 when Vallow Daybell's adopted son's grandmother, worried about his welfare, reached out to police. Vallow Daybell had been evasive when asked about her two youngest children.

Chad Daybell called 911 in October 2019 to report that his wife Tammy Daybell was battling an illness and died in her sleep. Her body was later exhumed, and an autopsy determined she died of asphyxiation.

Idaho police did a welfare check on the kids in November 2019 and discovered they were missing and hadn't been seen since early September. Vallow Daybell and Chad Daybell left town a short time later, eventually turning up in Hawaii without the kids. She was arrested in Hawaii in February 2020 on a warrant out of Idaho.

Defense attorneys told jurors that she was a “kind and loving mother” who happened to be interested in religion and biblical prophesies.

A witness at the Idaho trial said Vallow Daybell believes evil spirits have taken over people in her life and turned them into “zombies.”

When is the other trial in Arizona

Vallow Daybell is scheduled to go on trial again in late May on a charge of conspiring to murder Brandon Boudreaux. She has pleaded not guilty. If convicted, she would face a life sentence. ____ Associated Press writer Rebecca Boone in Boise, Idaho, contributed to this report. ____
